PIPE-COUPLING.

SLPECIFICATION forming part of Letters Patent No. 323,567, dated August'4, 1885.

Application filed June 3, 1885.

T0 all 1072.071?, it may concern,.-

Be it known that I, MICHAEL DILLENBURG, of the city and county of SanFrancisco, State oi' California, have invented an Improvement inPipe-Couplings; and I hereby declare the following to be a full, clear,and exact description ofthe same.

My invention relates to the class of couplings for pipes, and itconsists of a split sleeve titting on the pipe, and having a conical orwedge-shaped exterior surface, a head having a correspondingly-shapedaperture, in which the sleeve is seated, a tubular connecting sleeve orlink fitting upon the end of the pipe and seated within the innerportion of the aperture of the head, which is made with a plane surfaceto receive it, a washer between the tubular connecting-sleeve and thesplit sleeve, and tie-bolts connecting the two heads, all oi' which Ishall hereinafter fully explain by reference to the accompanyingdrawings, in which- Figure l is a view of my coupling, one half beingshown in section and the other half in elevation. Fig. 2 is a front viewof the split sleeve.

The object of my invention is to provide a simple and edectivepipe-coupling without having to resort to threading the pipes. Thecoupling is a two-part one, the parts on one side being the counterpartof those on the other. I shall, therefore, for the sake of clearness,use the singular number in describing them.

A is the pipe. B is the split sleeve, having its exterior surface of awedge or conical shape. The sleeve is fitted on the pipe, with its baseor portion oi largest diameter adjacent to the end to be coupled, thoughremoved therefrom a short distance.

Gis the head. It consists of a casting or other piece having a centralaperture, c. The inner portion of the aperture has a perfectly plane orparallel surface, whence said aperture continues in a conical shape,corresponding to the shape of the split sleeve B, which is seatedtherein.

Around the end of the pipe and against the inner end of the sleeve is awasher, D.

E is the tubular sleeve or connecting-link,

(No modi-l.)

Vconsisting of a short section oi' pipe. It is seated within the planeor parallel portion of the aperture of the head, and encircles the endofthe pipe and bears against the washer.

F are the tie-bolts between the two heads, and f are the nuts by whichthe bolts are set The operation of the device is as follows: Bytightening up the bolts the heads are drawn together, which, acting onthe connecting- 6o sleeve E, causes said sleeve to force the splitsleeves apart. These, being confined in the conical aperture of theheads, bind the tighter upon the pipes and hold them. The washersprevent any leak.

This device is applicable to the coupling of a pipe onto an elbow asWell as to another pipe.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a pipe-coupling, the combination of the split sleeve B, Jfitted onthe pipe, and having a conical or wedge-shaped exterior surface, thehead C, having a correspondinglyshaped aperture, in which the sleeve isseated, the tie-bolts F, for setting up the head, and the tubularconnecting-sleeve E, seated in thehead and upon the inner end of thepipe, substantially as herein described.

2. In a pipecoupling, the combination ol the split sleeve B, fitted onthe pipe, and having a conical or wedge shaped exterior surface, thehead C, having a correspondinglyshaped aperture, in which the sleeve isseated, the tubular connecting-sleeve E, seated in the 8 head on theinner end of the pipe, and the washer D between the connecting-sleeveand the split sleeve, substantially as herein described.

In a pipe-coupling, the split sleeve B, fitted on the pipe, and having aconical or wedge-shaped exterior surface, and the tubularconnecting-sleeve E, iitted on the inner end ofthe pipe, in combinationwith the head C, having an aperture, one portion of which has 95 aconical shape for seating the split sleeve, and the other portion has aplane or parallel surface for seating the connecting-sleeve,substantially as herein described.

4:. A pipe-coupling comprising the split roo sleeve B, fitted on thepipes, and having a and nuts f, by which the heads are forced toconiealor wedge-shaped exterior surface, the gether, substantially as hereindescribed. 1o heads C, having conical-shaped apertures, in In witnesswhereof I have hereunto set my which the sleeves are seated, the'tubulareonhand.
